Use Amsoil 15W-40 Marine/Diesel oil. The 5W-40's oils are not recommended in OBS 7.3 Power Strokes.
Yes you can get some really long oil change intervals when you use the by-pass filtration systems. Some of the commercial over the road truckers are getting 200k to 300k oil change intervals with the synthetic oils & by-pass filtration systems. Just make sure you spend the money for a very good system, like everything else in life ya get what ya pay for!
It's not unreasonable to get 20k - 30k miles between changes with Synthetic (abotu 2 years for me, I don't really drive much). The key is the bypass filter.
If it's shorter then it's shorter. I know synthetics are good stuff, nothing like dino oil.
would you run the rotella 5w30 synthetic this long with a bypass filter?
this is the only oil my truck has ever had, 3,000 mile changes for the first 60,000 miles than when I got it I went to 5,000 mile chnanges.

Here in the cold 5w40 is okay.
TJBeggs runs it in the winter time. I trust his judgement.
